Oknife LK Review: A Folding Knife and Flashlight in One Pocket Tool

Introduction

If a flashlight company set out to make knives, what would the next step look like? For Oknife, the answer is the LK: a folding knife with a fully functioning flashlight built right into the handle. It is a grab-and-go solution for the two items most people toss in their pockets before heading out, and it may well be one of the most interesting EDC tools of the year.

A Serious Knife, Not a Gimmick

Plenty of past knife-and-light combos bolted one tool onto the other: a decent flashlight with a blade stuck to it, or a blade with a small light awkwardly attached. The Oknife LK avoids that trap entirely. The blade is M390 steel, a serious choice that shows the brand is taking the cutting side just as seriously as the lighting side.

The 2.5-inch blade has a beefy, modified profile with a recurve in the edge, a beautiful finished edge, a solid spine, and good jimping. Deployment happens through a subdued flipper tab or by depressing the button lock and using a little inertia. The button lock also releases the blade for closing. A stainless steel deep-carry pocket clip rounds out the package.

The Built-In Flashlight

The headline feature is a lensed flashlight integrated into the front of the handle. This is not a dim, bumpy LED add-on: with a 400-lumen high mode and a defined hot spot, the beam genuinely reaches out some distance and works as a real task light. You can navigate by it and actually get work done.

Operation is simple. A single push turns it on, with low and high modes. The button sits recessed below the handle surface, so it is not easy to fire accidentally in a pocket. For extra security, holding the button for a few seconds locks the light out; a push then only gives a locked indicator. Hold it again to unlock and it is ready to go.

Charging happens over USB-C through a fully exposed port on the back, which suggests real confidence in its durability.

RGB Modes and Party Light

Beyond the standard white output, a triple click cycles through a set of RGB settings, moving through purple, orange, yellow, green, and blue. Holding the button switches to a spinning multi-color party mode that toggles through a handful of colors.

It is a playful extra rather than a core reason to buy, but it adds flexibility for signaling or low-light situations where color helps.

Things to Consider Before Buying

The LK weighs just 3 oz (86 g), which is impressively light for a tool packing a knife and a battery-powered light. The main trade-off is thickness: one side of the handle is a little thicker because the battery pack has to fit inside. That is worth thinking about if you prefer a perfectly symmetrical folder.

The finish shown here is the MAO Desert White colorway, with a clean, beautiful execution throughout.

Who the Oknife LK Is For

This tool makes sense for anyone who carries both a knife and a flashlight daily and wants to simplify. Instead of two pocket items, you grab one. It is also a strong pick for campers, travelers, and anyone who values having a genuine work-capable light always on hand.

Buying Advice

The Oknife LK works because neither half feels like a compromise. Olight is clearly taking both the flashlight and the knife seriously, and the result is a tool that could point the direction for the whole category. If you carry both items anyway, this is an easy way to consolidate without giving up capability on either side.

Conclusion

The Oknife LK looks like a gimmick on paper, but the execution genuinely holds up: M390 blade steel, a real 400-lumen lensed light, RGB modes, a pocket-safe lockout, and USB-C charging in a 3 oz package. For everyday carry users who want one tool instead of two, it is an outstanding option.
